Throw an alternator on it, a Powermaster HO unit is your ticket. These cars' 105a OEM units were barely adequate. 04 Escalade unit is a cheap upgrade too.

The CVF units have a lifetime warranty, so I have to start that process. And their units are 170 amp. Once I replace, I'll see how it goes. I have a rather large stereo in the car as well. If I run into issues with the lights on and the stereo up, I'll go with a Powermaster or Mechman

I second the Powermaster recommendation, if the warranty route doesn't work out. Powermaster is a quality product, it's the only brand of aftermarket alternator I will buy.

CVF is warrantying the alternator no questions asked. GREAT service. As soon as I get the replacement installed, I'll report back.

Unfortunately, I do not know yet. With car show season, I haven't been able to swap it yet. After I drive it, I remove the main battery wire and put it on the battery tender. Should know in a month or so.
